We track six criteria pollutants considered harmful to public health and the environment. Those include carbon monoxide, nitrogen dioxide, ozone, particulate matter (10µm or less and 2.5µm or less), as well as sulfur dioxide.

The Air Quality Index (AQI) is the official index for air quality across the United States. The AQI ranges from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern.

Pollen

A measure of how much pollen is in the air in a certain area at a specific time. It is expressed in grains of pollen per square meter of air collected over 24 hours. Pollen counts tend to be highest early in the morning on warm, breezy days and lowest during chilly, wet periods.

Flu Activity

This maps outbreaks of influenza (Flu) or increases in ILI cases and recent laboratory-confirmed influenza in at least half the regions of the state. Higher levels of activity can increase the risk of contagion.

{{ fluData.flu_activity }}

No laboratory-confirmed cases of influenza and no reported increase in the number of cases of ILI.

Small numbers of laboratory-confirmed influenza cases or a single laboratory-confirmed influenza outbreak has been reported, but there is no increase in cases of ILI.

Outbreaks of influenza or increases in ILI cases and recent laboratory-confirmed influenza in a single region of the state.

Outbreaks of influenza or increases in ILI and recent laboratory confirmed influenza in at least two but less than half the regions of the state with recent laboratory evidence of influenza in those regions.

Outbreaks of influenza or increases in ILI cases and recent laboratory-confirmed influenza in at least half the regions of the state with recent laboratory evidence of influenza in the state.

UV Index

The UV Index is a forecast of the probable intensity of skin damaging ultraviolet radiation reaching the surface during the solar noon hour. The greater the UV Index, the greater the amount of skin damaging UV radiation. The threshold for skin damage is dependent on several factors, including skin tone. Note that clouds do not block most UV light.

Wind Chill & Heat

Wind Chill is the decrease in temperature felt by the body due to wind removing heat from exposed skin. Heat index combines temperature and humidity data to account for the effects of heat not evaporating from the body.
